WebMay 31, 2024 · Abstract. Cancer cells have upregulated glycolysis compared with normal cells, which has led many to the assumption that oxidative phosphorylation (OXPHOS) is downregulated in all cancers. However, recent studies have shown that OXPHOS can be also upregulated in certain cancers, including leukemias, lymphomas, pancreatic ductal … WebThis may imply that COPD AMs may have more available glucose intermediates to harness glycolysis in the absence of OXPHOS to generate the ATP required for efferocytosis. Consistently, oligomycin, an inhibitor of OXPHOS, suppressed efferocytosis in MDMs, whereas inhibiting glycolysis suppressed efferocytosis only when OXPHOS was blocked.
